| Summary: | This paper presents a simple methodology of ex
in vitro testing of a Low Contact Stress (LCS) Mobile-Bearing
Total Knee System, produced by DePuy Orthopaedics, Inc.
USA, on an experimental stand. To be tested LCS MobileBearing
Total Knee System was designed and constructed two
auxiliary devices. Testing the LCS System was made taking
into account the provisions of international standards. The
method for determining the degree of wear of the polyethylene
component of the LCS System supposes several essential steps:
cleaning and sterilization of the components (metallic and
polymeric) of LCS System; weighing of polyethylene
component; visual inspection of articulating surfaces;
determining the average roughness of contact areas;
determining the overall size of the system on a coordinate
measuring machine (optional); performing a large number of
cycles on experimental stand and determining of the specific
parameters of wear and comparing them with data from the
literature. |
